Trigger finger is a type of tendinitis which develops in the tendons which bend the fingers. It is a common problem because of the way that the hand is made, which may be a little different than you would suspect. There are no muscles in the fingers themselves. We actually move our fingers by remote control. Muscles in the forearm are connected to the finger bones by smooth, flexible strings, called tendons. The muscles pull on the tendons, which then bend the finger joints.
- Tendon swelling (tendinitis) results from a person’s own tendency to collect fluid around their tendons and joints.
- This may be aggravated by repetitive or strenuous activities. When the tendons which bend the fingers (the flexor tendons) become irritated, they can cause pain, swelling, and stiffness.
- Tendon swelling interferes with the normal movement of the tendons and can cause the finger to and click, catch (“triggering”) or lock in position.
- Ice for five to fifteen minutes at a time on the area which is most swollen and tender.
- “Over the counter” non-steroidal anti inflammatory medication (NSAID), such as aspirin, ibuprofen, naprosyn, or ketoprofen. Check with your pharmacist regarding possible side effects and drug interactions.
- Avoid activities which involve a sustained grip. Hold off on the use of grip strengthening devices or exercises involving repetitive squeezing – these put stress on the irritated tendon.
- If fingers bend and lock during the night and are painful to straighten in the morning, it may be helpful to wear a splint to keep them straight while sleeping. One way to do this is to use a wrist support splint as shown below: A wrist splint designed to be worn on the opposite hand may be worn with the forearm end turned out to form a palm sided support for the fingers. This may be helpful as an interim measure.
